The fabled fifth East London Line carriage is here. London Overground confirms that "the first of the five-car trains is now in service between Highbury & Islington and West Croydon/Clapham Junction/Crystal Palace/New Cross."

BC is still trying to eke out the last few cycles to work before the cold and Christmas parties render the journey uncyclable, so please let us know if the arrival of the fifth carriage has started to make a difference to your journey?
